+Expat can be built on Windows in two ways:
+  using MS Visual Studio .NET or Cygwin.
+
+* Cygwin:
+  This follows the Unix build procedures.
+
+* MS Visual Studio 2013, 2015 and 2017:
+  A solution file for Visual Studio 2013 is provided: expat.sln.
+  The associated project files (*.vcxproj) reside in the appropriate
+  project directories. This solution file can be opened in VS 2015 or VS 2017
+  and should be upgraded automatically if VS 2013 is not also installed.
+  Note: Tests have their own solution files.
+
+* All MS C/C++ compilers:
+  The output for all projects will be generated in the win32\bin
+  directory, intermediate files will be located in project-specific
+  subdirectories of win32\tmp.
+  
+* Creating MinGW dynamic libraries from MS VC++ DLLs:
+  
+  On the command line, execute these steps:
+  pexports libexpat.dll > expat.def
+  pexports libexpatw.dll > expatw.def
+  dlltool -d expat.def -l libexpat.a
+  dlltool -d expatw.def -l libexpatw.a
+  
+  The *.a files are mingw libraries.
+
+* Special note about MS VC++ and runtime libraries:
+
+  There are three possible configurations: using the
+  single threaded or multithreaded run-time library,
+  or using the multi-threaded run-time Dll. That is, 
+  one can build three different Expat libraries depending
+  on the needs of the application.
+
+  Dynamic Linking:
+
+  By default the Expat Dlls are built to link statically
+  with the multi-threaded run-time library. 
+  The libraries are named
+  - libexpat(w).dll 
+  - libexpat(w).lib (import library)
+  The "w" indicates the UTF-16 version of the library.
+
+  One rarely uses other versions of the Dll, but they can
+  be built easily by specifying a different RTL linkage in
+  the IDE on the C/C++ tab under the category Code Generation.
+
+  Static Linking:
+
+  The libraries should be named like this:
+  Single-theaded:     libexpat(w)ML.lib
+  Multi-threaded:     libexpat(w)MT.lib
+  Multi-threaded Dll: libexpat(w)MD.lib
+  The suffixes conform to the compiler switch settings
+  /ML, /MT and /MD for MS VC++.
+  
+  Note: In Visual Studio 2005 (Visual C++ 8.0) and later, the
+  single-threaded runtime library is not supported anymore.
+
+  By default, the expat-static and expatw-static projects are set up
+  to link statically against the multithreaded run-time library,
+  so they will build libexpatMT.lib or libexpatwMT.lib files.
+
+  To build the other versions of the static library, 
+  go to Project - Settings:
+  - specify a different RTL linkage on the C/C++ tab
+    under the category Code Generation.
+  - then, on the Library tab, change the output file name
+    accordingly, as described above
+
+  An application linking to the static libraries must
+  have the global macro XML_STATIC defined.
